FASTENING DEVICE.

SPECIFICATION forming part of Letters Patent No. 369,348, dated September 6, 1887.

Application filled April 7, 1886. Serial No. 193,152.

To all whom, it may concern.-

Be it known that I, Gnonon Lrenrnrsnn, a citizen of the United States, residing at Napoleon, in the county of Henry and State of Ohio, have invented a new and useful Inr provement in Fastening Devices, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in fastening devices; and it consists of the peculiar and novel construction and combination of parts, substantially as hereinafter fully set forth, andspecifically pointed out in the claim.

The primary object of my invention is to provide an improved fastening device for connecting iron and wood together in the manufacture of school-desks and seats for the same, or church or camp-meeting benches or pews, where it is desirable to readily and quickly take the parts apart or separate them, so that they can be readily transported, packed together, or stored away.

A further object of my invention is to provide a device of the class named which can be readily and quickly put or fastened together by an unskilled person with a hammer and without the aid of screws or bolts, which device shall firmly and rigidly hold the parts together without the shaking or loose motion which is so common and objectionable in desks and seats.

In the accompanying drawings I have shown a school-desk having my invention applied thereto; but it will be understood that I do not confine myself to the use of my invention in connection with school-desks.

Figure l is a perspective View of my improved fastening device applied to a desk. Fig. 2 is an enlarged detached view of the fastening device. Fig. 3 is a sectional view on the line a; a: of Fig. 2.

Referring to the drawings, in which like letters of reference denote corresponding parts in all the figures, A designates the arm or standard,which is made of metal, of a school-desk, seat, or other like apparatus; and B, the wood board or block which is to be detachably and rigidly connected to the metallic arm or standard A. The wood block or board B is provided with a transverse recess or slot, I), having an enlarged end, so as to provide a shoul- (No model.)

der or ledge, b, at a distance beneath one of the outer faces of the board or block B.

O designates a connecting-plate, which is preferably made rectangular, as shown and provided with a square or oval head, 0, the plate being slotted longitudinally, as at e, to receive a fastening-key, E, the plate and its head being formed or cast from a single piece of metal.

The slotted end of the plate is passed through the recess 1), and the head 0 bears on the shoulder or ledge 21 to limit the forward movement of the plate, said head fitting snugly and closely within the socket or recess and flush with the outer face of the wood board or block 13, the

recess 2) therein being cut or formed transversely across the grain, so as to obviate the danger of the block splitting or breaking when the plate 0 is forced or driven home in the socket or recess.

The standard or arm A is usually provided with a strengthening rib or flange, a, and through the standard and its rib are formed openings cf, respectively, which are arranged at the same point thereon and at right angles to each other. The opening 6 in the standard is arranged at the edge or angle where the rib joins the standard,and the openingfin the rib is located at the same point and at right angles to the opening 6.

When the wood board or block B and the metal standard or'arm A are to be secured together, they are arranged at right angles to each other, as clearly shown, and the plate 0 is passed through the recess Z2 and the opening 6 in the standard, so that it will bear or abut against one of the faces of the rib a, and its slot 6 will register or coincide with the open ing f in the rib, when a metallic key, F, is driven through the openings f e to rigidly and firmly secure the parts together.

From the foregoing description, taken in connection with the drawings, it will be ob served that the fastening device can be easily and rapidly put or connected together and as easily taken apart by an unskilled person with a hammer or other suitable implement, and as all of the parts that are acted upon by the key are of metal, they are held very rigidly and. immovably together.

The improved fastener can be employed for ICO a number of purposes and in other relations than the device herein shown-as, for instance, 'in securing a metallic band, shoe, or strip to a wooden runner of a sleigh or sled and in securing the knees to the runner and bolster of the frame, or in setting up church pews, benches,- or rows of seats, and, in fact, in any relation where it is desirable to connect one piece or part of a device which is made of wood to a metallic part so that the parts can be readily taken apart and put together.

I am aware that it is old to attach the wood part of a school-desk to the iron part by a bolt having its head seated in the wooden part and passing through a slot in the metallic part, combined with a nut to screw on the end of the bolt to bear against the metallic part of the desk and hold the two parts together. This construction it is the object of my invention to overcome.

I am also aware that a key or wedge has been heretofore employed for various purposes, one instance of its use being as a nut-lock.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

.In a fastening device for school seats, desks, and the like, consisting of the part B, having slot b, in combination with the part A, having opening 6, registering with slot 1), the plate 0, having its head fitted to part B and its body passing through slots 1) e, arib, a, provided on the part A, against which rib the plate 0 rests, a slot, f, provided in the rib, a slot, 6, formed in plate 0, and a key or wedge passed through the slots 6 f, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

GEORGE LIGHTHISER.
